Microfluidic chip, the support system and method of implementation for a space 27 and rapid thermal regulation of a sample

摘要

The present invention proposes a device permitting a rapid regulation, spatially controlled and reproducible of the temperature of the sample or a viscous liquid, which can be used in the routine, according to a high rate and under satisfactory economic conditions, with improved reliability and allowing a logistics reliable in a laboratory. To this end, the invention is to provide a microfluidic chip of the heat regulation of a sample, characterized in that it comprises a layer of material of thickness, on one face of which is placed at least one array of micro - channels in which: • each microphone - channel has a width greater than or equal to 10 μm and less than or equal to 5 mm, each microphone - channel has a height greater than or equal to 10 μm and less than or equal to 500 μm, the distance between two micro - channels being less than or equal to 200 μm, and in that the layer of material carrying the micro - channels has either a thermal capacity per unit area, at 20°C. of less than 0,3 j.k - 1.cm - 2, or a thermal conductivity at 20°C, of less than or equal to 0,5 w.m - 1.k - 1 if it has a thermal capacity per unit area, at 20°C. higher than or equal to 0,3 j.k 1.cm - 2 -.
